YOKOGAWA EJA210E flange mounted differential pressure transmitter

The high performance flange mounted differential pressure transmitter EJA210E can be used to measure levels of densities of solidifying or precipitating liquids. EJA210E outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure. Its accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response, remote set-up using communications and self-diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available. All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.

Static Pressure Effects per 0.69 MPa (100 psi) Change 

Span Effects 

M and H capsules ±0.028% of span 

Effect on Zero 

M and H capsules ±0.007% of URL 

Stability 

±0.1 % of URL per 12 months 

Power Supply Effects(Output signal code D and J) 

±0.005 % per Volt (from 21.6 to 32 V DC, 350Ω) 

Response Time (Differential pressure)

M and H capsule: 120 ms (approximate value at normal temperature) When software damping is set to zero and including dead time of 45 ms (nominal)

Static Pressure Signal Range and Accuracy (For monitoring via communication or on indicator for BRAIN and HART communication type. Includes terminal-based linearity, hysteresis, and repeatability) 

Range 

Upper Range Value and Lower Range Value of the static pressure can be set in the range between 0 and Maximum Working Pressure (MWP*). The upper range value must be greater than the lower range value. Minimum setting span is 0.5 MPa (73 psi). 

Maximum Working Pressure (MWP) is within flange rating pressure. Accuracy 

Absolute Pressure 1 MPa or higher: ±0.5% of span Less than 1 MPa: ±0.5%×(1 MPa/span) of span 

Gauge Pressure Reference 

Gauge pressure reference is 1013 hPa (1 atm) 

Note: Gauge pressure variable is based on the above fixed reference and thus subject to be affected by the change of atomospheric pressure.
